The biosynthesis of Pt-nanoparticles (Pt NPs) supported on bovine bone powder was conducted by an environmentally friendly method that consists on immersing bovine bone powder into a Pt4+ metal ion solution at room temperature, atmospheric pressure and subsequent reduction by Heterotheca inuloides. It is worth pointing out that a calcination process is not required for the synthesis of this catalyst...
The behaviour of several Lewis acids, derived from zinc, aluminium and titanium, supported on silica gel, as catalysts of the Diels-Alder reactions of cyclopentadiene with methyl, (1R,2S,5R)-menthyl, and (R)-pantolactone (E)-2-cyanocinnamates has been compared. The best catalytic activities were observed with the zinc catalysts. The extent and even the direction of the asymmetric induction changes...
